Logger problems after changing hostname

My config: Zimbra 4.0.1 on FC5
I changed my hostname sometime back.
Everything is working except for the statistics in the zimbraAdmin interface.
Under Monitoring I still see the old hostname with the list of services dated to when I changed the name. I also see the new hostname with the list of services all active and with the current date/time.

When looking at the Server Statistics. The "System Wide Information" shows old statistics from the date I changed the hosts.
In the statistics for mail.new-host.com no statistics appear at all even though the change was made over 3 months ago. (broken images)

Running zmcontrol status. Shows that the logger is running but all data in the logger database seems to be old. The only table with the current date is the service_status table. All others are dated back to the hostname change date or older.

I have the old hostname server and the new on server statistics.
But my graphs dont work because they are pointing for the old server name.

here is the output of the the command:

And notice that my old_server_name don't show up anymore.
And the new name of the server dosent generate any data.
